Entropy driven key-lock assembly [PDF]
The Journal of Chemical Physics, 2008 The effective interaction between a sphere with an open cavity (lock) and a spherical macroparticle (key), both immersed in a hard sphere fluid, is studied by means of Monte Carlo simulations. As a result, a two-dimensional map of the key-lock effective interaction potential is constructed, which leads to the proposal of a self-assembling mechanism ...

Two-piece obturator using “lock-and-key” mechanism
The Journal of Indian Prosthodontic Society, 2017 This paper describes a method used for the fabrication of a two-piece denture obturator for a patient who had surgical removal of the premaxilla due to squamous cell carcinoma. The patient had been wearing a two-piece obturator but encountered difficulty

A Fuel‐Driven Lock‐and‐Key System [PDF]
ChemistryOpenThis study introduces a fuel‐driven lock‐and‐key system based on the interaction between crown ether and ammonium ion. In this simple model system, a key‐like molecule with an amino group functions as the key, while 15‐crown‐5 serves as the lock.

Molecular Docking: From Lock and Key to Combination Lock
Journal of Molecular Medicine and Clinical Applications, 2018 Accurate modeling of protein ligand binding is an important step in structure-based drug design, is a useful starting point for finding new lead compounds or drug candidates. The 'Lock and Key' concept of protein-ligand binding has dominated descriptions of these interactions, and has been effectively translated to computational molecular docking ...

A DNA dual lock-and-key strategy for cell-subtype-specific siRNA delivery
Nature Communications, 2016 Delivery of siRNA to target cells is essential for in vivogene therapy. Here the authors demonstrate an oligonucleotide aptamer that targets therapeutic siRNA to a specific cell type.

A Secure Scan Architecture Protecting Scan Test and Scan Dump Using Skew-Based Lock and Key
IEEE Access, 2021 Scan-based Design for Testability (DFT) is widely used in industry as it consistently provides high fault coverage. However, scan-based DFT is prone to security vulnerabilities where attackers use the scan design to obtain secret information from the ...

Acoustically levitated lock and key grains
Physical Review Research, 2023 We present a scheme for generating shape-dependent, specific bonds between millimeter scale particles, using acoustic levitation. We levitate particles in an ultrasonic standing wave, allowing for substrate-free assembly.
